Confirm for me that if I install an after market fuel gauge with a new in tank sending unt with the same OHMS, it should work. While I'm here, do you know of anyone that sells rectuglar fuel gauges that operate by wiring, and not circuit board? 3. Know if anyone that could put my DeSoto fuel gauge face on an after market gauge. K.I.S.S.

Thank you. Very helpful info. So far as I can tell, the original tank unit looks good, but have not been sucessful finding what the ohmns are on the original gauge. K.I.S.S.
